The Agilent E1441A has standard built-in waveforms including Sine, Square, Triangle, Ramp, Noise, Sin (x)/x, exponential rise and fall, Cardiac and DCV. With the E1441A you can also design your own arbitrary waveforms. Standard features of the E1441A include internal AM/FM/FSK/Burst modulation and both linear and logarithmic sweep. The output from the Agilent E1441A is isolated from earth ground so that ground loops or other common mode noise are minimized. Some of the features of the E1441A are:
